Abstract

A soybean extract, its manufacturing method and its application, which could inhibit tumor growth, adjust immunity. The method comprises: preparing the raw material and lixiviating solution, lixiviating, purifying and concentrating. The prepared extract contains soyhean isoflavone, oligosaccharide and polysaccharide. Health food prepared by the extract has good taste.

Description

(1) Technical field [0001] The present invention belongs to the field of health care and also relates to the field of deep processing of soybeans. More specifically, the present invention relates to a variety of health care functions such as preventing and treating cardiovascular and cerebrovascular diseases, inhibiting tumor cell growth, eliminating edema and women's menopausal syndrome, and regulating human immunity. The soybean extract, the manufacturing method of the soybean extract and the use of the soybean extract. (2) Background technology [0002] Soybean originated in my country and has been cultivated for more than 5,000 years as an important food source. Because it is rich in protein and has a good amino acid composition, soy protein is widely developed and used in many developed countries and regions. Soy protein is widely used in meat products, fish products, dairy products and other foods, including beverages and cold drinks and other food industries. [0003] In a...
